Remove a saved Connection
RemoveConnection( name, opts )
string; the identifier for the connection to remove
(optional) an equation of the form filename=string
RemoveConnection deletes the connection associated with identifier name from a file of connections created with calls to Save.
RemoveConnection requires that an identifier be specified. This differs from Save and LoadConnection. These functions assume an identifier of "default" if one is not given.
RemoveConnection accepts one optional argument.
filename = string
used to specify the file from which this connection is removed. When no filename is given, connections will be loaded from "$HOME/maple/toolbox/Database/data/default.con", where $HOME is the value returned by kernelopts( homedir ).
Create a connection.
driver ≔ DatabaseLoadDriver⁡:
conn ≔ driver:-OpenConnection⁡url,name,pass:
Save the connection to disk using the default file and the default identifier.
Close the connection.

Attempt to re-establish the connection saved as default.
