Error message on BeautifulTable.column_headers should change #137
Description
If I use column_headers I get this error message:
FutureWarning: 'BeautifulTable.column_headers' has been deprecated in 'v1.0.0' and will be removed in 'v1.2.0'. Use 'BTColumnCollection.header' instead.
Should have been:
FutureWarning: 'BeautifulTable.column_headers' has been deprecated in 'v1.0.0' and will be removed in 'v1.2.0'. Use 'BTColumnCollection.columns.header' instead.
Notice the .columns. part
