read Elastic materials declaration for blocks and meshsets

File parameters:

[block_1]
displacemet_order = 1/2 .. N
material = KIRCHHOFF/HOOKE/NEOHOOKEAN
young_modulus = 1
poisson_ratio = 0.25
density = 1
a_x = 0
a_y = 0
a_z = 10

To read material configuration file you need to use option:

-elastic_material_configuration name_of_config_file
