Dynamic Node sizing and/or text label sizing #13

Description

Long connector labels are crowded if the string length is substantial.

label-crowding

Proposed Solution

• Add some constraints to the text labels to allow them to wrap and not overlap/collide
• Provision for the Node to size itself to its contents dynamically, perhaps with some settable min/max size limits.

Describe Alternatives You've Considered

No alternatives are possible aside from manual truncation of the string prior to assigning it to the Node's input/output labels.
