bug-19720-RemoveDeprecatedIOUtilStrings

Okay. Just a hint for the future: These unsigned int / int comparisons often occur when there is a semi-unknown type involved, for example, any typedef one is too lazy to look up. C++11 decltype comes to the rescue:

old: for(int c=0; c<matrix.ColumnDimensions; c++)
new: for(decltype(matrix.ColumnDimensions) c = 0; c < matrix.ColumnDimensions; ++c)

This does not seem to work:
error: increment of read-only variable ‘c’

But it works with auto:
for(auto c = decltype(matrix.ColumnDimensions){0}; c < matrix.ColumnDimensions; ++c)

Remove deprecated strings in IOUtil

That's because the type seems to be const. For this case please use std::remove_const in the future.

Can we remove all the rest of the deprecated code now as well?

std::remove_const isn't working in this context. However, until itkMatrix colum/row index is surely of type unsigned int we should use it directly!
