## Detailed Description

### template<class ValueType>
class eoValueParam< ValueType >

eoValueParam<ValueType>: templatized derivation of eoParam.

Can be used to contain any scalar value type. It makes use of std::strstream to get and set values. This should be changed to std::stringstream when that class is available in g++.

Note also that there is a template specialization for std::pair<double, double> and for std::vector<double>. These stream their contents delimited with whitespace.
