edited documentation

cleaned up old topo to sp lines method
added pts.poly.arcs.dist function
added maptools dependency
added bitops dependency
separating plotting and processing in arc distance functions
a sloppy commit
debugging after adding a bunch of functions
finally have pariwise plotting down-and some new functions
changed to bitflipper2 for a rcp.idx to get index consistent with R’s vectors for 3rd column in matrix output
new function: prcnt.wthn.idx - given points and arc, gets percent within a given percentile
changed within distance function to return logical the same size as input points, instead of index of true values.
