Renamed rotation_matrix_zyz() to R_euler_zyz().

This name is more descriptive and is a better naming scheme for rotation matrices constructed using
other inputs.

Wrote a new function R_2vect() to generate a rotation matrix from 2 vectors.

This rotation matrix is not unique because of axially symmetry allowing the rotation axis to be any
vector within the symmetry plane, so the cross product with the axis-angle convention is used to
define this matrix.

Started writing the generic_fns.structure.cone_edge() function.

This function generates a geometric shape constructed from atoms to be embedded into a PDB file,
representing the outer edge of the cone.
