Initial attempt

Initial coded solution to clipping a full resolution raster DEM to the
spatial extent of a user-defined buffer of the point features.
Unit fix

Adjusted unit label on buffersize to fix error.
File extension appended

Appended .shp to va_rAll_buf files to fix error.
First attempt at generalization

Removed some hard-coded paths. Hard-coded buffer size now stored as a
variable. Minor documentation corrections.
Changed drive letter for new computing environment
Changed folder names, updated paths

Brought branch fulldem_clip more in line with master. Will be merged.
Still need to get dem clip to work correctly.
Resolved conflicts, updated paths
