Basic Simulation of Soil Profile Data in R via AQP

Something fun to play with before the new year: experimental code in aqp for simulating soil profile data from a single "template" profile. The basic idea: simulate horizon thickness data using a family of Gaussian functions with mean defined by horizon thickness values found in the template and standard deviation defined by the user. Larger hz.sd values will yield more drastic variation in the simulated results. Note that only "horizonation" (e.g. the sequence of horizons and their respective thickness) is simulated; horizon attributes (e.g. texture, pH, etc.) are copied from the "template" profile.

Basic usage is demonstrated below, see package manual page for details. This function is only available in the version of aqp hosted by R-Forge. It should be on CRAN by the new year.
