Geometry directory contains several versions of several meshes, and filenames are not sufficiently descriptive

[tkuchida]

For example, the 5 tibia files are

• l_tibia.vtp
• r_tibia.vtp
• tibia.vtp
• tibia_l.vtp
• tibia_r.vtp

What's the difference between "r_tibia" and "tibia_r"? For which leg is the generic "tibia" intended? Cleaning up this directory and using descriptive filenames might help prevent issues like #2.

I have updated the tibia files in #74. I will investigate the femur geometries in a subsequent PR. Thanks, Tom.

Re-opening, as this Issue affects many meshes (5 femur, 7 clavicle, 6 humerus, 6 radius, 19 "fingers", etc.).
