15 * Define a meshs.
16 *
17 * A mesh is a regular grid representing cells of the same width (in x) and of the same height
18 * (in y). At each mesh point is associated a value.
19 *
20 * Each axis of the mesh is defined by a minimum value, a number of values is a mesh step.
21 * For example: if min = 1, nbValues = 5 and step = 2 => the axis of the mesh will be [1, 3, 5,
22 * 7, 9].
23 *
24 * The values are defined in an array of size {nbX * nbY}. The data is stored along the X axis.
25 *
26 * For example, the mesh:
27 * Y = 2 [ 7 ; 8 ; 9
28 * Y = 1 4 ; 5 ; 6
29 * Y = 0 1 ; 2 ; 3 ]
30 * X = 0 X = 1 X = 2
31 *
32 * will be represented by data [1, 2, 3, 4, 5, 6, 7, 8, 9]
