command line interface to make a new material

[saransh13]

The usage is as follows:

usage: hexrd make-material [-h] [-f FILE] [-x XTAL]

make a new material file in the hdf5 format using the command line. user specifies the file and crystal names

options:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  name of h5 file, default = test.h5
  -x XTAL, --xtal XTAL  name of crystal, default = xtal```

The command line guides the users through a series of informational prompts and question. Here is an example for making a Ni crystal with isotropic Debye-waller factors

```(hexrd) szechuan:Desktop soderlind3$ hexrd make-material --file test.h5 --xtal Ni

  This is a program to create a HDF5 file for storing crystallographic information.
  The following inputs are required:
          Crystal System:
                 1. Cubic
                 2. Tetragonal
                 3. Orthorhombic
                 4. Hexagonal
                 5. Trigonal
                 6. Monoclinic
                 7. Triclinic

         Space group number
         Atomic number (Z) for all species in unit cell
         Asymmetric positions for all atoms in unit cell
         Debye-Waller factors for all atoms in the unit cell
         You'll be prompted for these values now

 Note about the trigonal system:
 -------------------------------
 Primitive trigonal crystals are defined with respect to a HEXAGONAL
 reference frame.  Rhombohedral crystals can be referenced with
 respect to a HEXAGONAL basis (first setting), or with respect to
 a RHOMBOHEDRAL basis (second setting).  The default setting for
 trigonal symmetry is the hexagonal setting.  When you select
 crystal system 5 above, you will be prompted for the setting.
