Converts a DataFrame named df to a TimeArray named ta keeping only columns defined using colnames and using colums defined using timestamp as timeseries index.

Optional parameters

• colnames: If it's not given, all columns will be kept.
• timestamp: If it's not given, column named :Date will be used as timeseries timestamp index.

Convert TimeArray (from TimeSeries.jl) to DataFrame (from DataFrames.jl)
