Determine which methods should be required by the ILayout interface

[GoogleCodeExporter]

We need to eliminate our reliance on casts to BaseLayout and AbstractLayout
in the core in favor of casts to ILayout. To make this a reality we need to
evaluate which methods need to be included in the interface and which
should be removed.

Methods to be removed:
- bounds

Methods that need further discussion:
- dataField
- labelField
- referenceRepeater
- currentReference
- currentValue
- currentLabel
- dataTipLabelFunction
- dataTipPositionFunction

We should consider splitting the debated method over other interfaces which
better encapsulate the intention of those methods.

ILayout is no more.
