minorAxisTicks

Compute pretty mark locations for minor ticks, based on the way
that traditional R graphics do it.

Includes bases for litholog generation: graphical functions
based on R base graphics, interval management functions and svg importation
functions among others. Also include stereographic projection functions,
and other functions made to deal with large datasets while keeping options
to get into the details of the data.
