Create a simple visualization and transformation tool for meshes, stored in obj. file format.

Structures
implement math types Mat4 and Vec4. Add functions Multiply(Mat4, Mat4) and Multiply(Vec4, Mat4).
implement IndexedFace which contains array of Vec4 vertex positions and array of Int indices
Mesh import and display
load mesh from Wavefront file (.obj). [Download test models here]. Assume that all imported models are scaled to box (2x2).
display wireframe model in the center of a screen so that Y-axis of model directs upwards and X-axis directs right. (Z is ignored)
Transformations - must be implemented using matrix multiplication!
Add buttons which can control transformations of the model. It must include
Always remember the original transformation and reset it using a button
Examples of the functional program
screen 1 = Import only
screen 2 = Import only
screen 3 = Imported, translated by -0.6 in X-axis, rotated by 0.6 rad around Y-axis, rotated by 0.4 rad around Z-axis and scaled by factor 1.1, in order
