Add a variable with DataType = String to the file. Must be in define mode.
The variable will be stored in the file as a CHAR variable.
A new dimension with name "varName_strlen" is automatically added, with length max_strlen.

@param varName    name of Variable, must be unique within the file.
@param dims       list of Dimensions for the variable, must already have been added. Use a list of length 0
for a scalar variable. Do not include the string length dimension.
@param max_strlen maximum string length.
@return the Variable that has been added
Add a variable with DataType = String to the file . Must be in define mode . The variable will be stored in the file as a CHAR variable . A new dimension with name varName_strlen is automatically added with length max_strlen .
