Giagantic changes that update Dowa library to be more align with stb style array and hashmap. Updated Seobeo to be caching on server side instead of file level caching. Deleted bunch of things I don't really use.

5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	2 *
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	3 * raymath v2.0 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	4 *
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	5 * CONVENTIONS:
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	6 * - Matrix structure is defined as row-major (memory layout) but parameters naming AND all
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	7 * math operations performed by the library consider the structure as it was column-major
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	8 * It is like transposed versions of the matrices are used for all the maths
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	9 * It benefits some functions making them cache-friendly and also avoids matrix
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	10 * transpositions sometimes required by OpenGL
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	11 * Example: In memory order, row0 is [m0 m4 m8 m12] but in semantic math row0 is [m0 m1 m2 m3]
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	12 * - Functions are always self-contained, no function use another raymath function inside,
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	13 * required code is directly re-implemented inside
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	14 * - Functions input parameters are always received by value (2 unavoidable exceptions)
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	15 * - Functions use always a "result" variable for return (except C++ operators)
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	16 * - Functions are always defined inline
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	17 * - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	18 * - No compound literals used to make sure libray is compatible with C++
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	19 *
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	20 * CONFIGURATION:
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	21 * #define RAYMATH_IMPLEMENTATION
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	22 * Generates the implementation of the library into the included file.
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	23 * If not defined, the library is in header only mode and can be included in other headers
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	24 * or source files without problems. But only ONE file should hold the implementation.
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	25 *
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	26 * #define RAYMATH_STATIC_INLINE
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	27 * Define static inline functions code, so #include header suffices for use.
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	28 * This may use up lots of memory.
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	29 *
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	30 * #define RAYMATH_DISABLE_CPP_OPERATORS
5695ef413be0 Initialized mono repo with bazels with few examples. June Park <parkjune1995@gmail.com> parents: diff changeset	31 * Disables C++ operator overloads for raymath types.
