- turn idma_box_mean.m and idma_box_subset.m into functions.
- add help to the each function.

1 function [p]=idma_float_plot(nameFloat);
2 %
3 % IDMA_FLOAT_PLOT extracts the time series of one float
4 % (e.g. '4900828') from argo_feb2013_2008_to_2010_model.nc
5 % and return the result in MITprof format (p)
6 %
7 % Example: [p]=idma_float_plot('4900828');
8 %
9 % Other float examples: '4900829', '4900830', '4900831'
