Piecewise linear transformation for distance matrices, utility function for geco.

piecewiselin(distmatrix, maxdist=0.1*max(distmatrix))

`distmatrix`	symmetric (non-negative) distance matrix.
`maxdist`	non-negative numeric. Larger distances are transformed to constant 1.

Transforms large distances to 1, 0 to 0 and continuously linear between 0 and maxdist.
