class QgsMapLayerStyleManager : QObject
{
%Docstring
Management of styles for use with one map layer. Stored styles are identified by their names. The manager
always keep track of which style of the stored ones is currently active. When the current style is changed,
the new style is applied to the associated layer.

The class takes care of updating itself when the layer's current style configuration changes.
When some of layer style's properties change (e.g. opacity / colors), the style manager will
record them in the currently active style without any extra effort required.

When an instance is created, it creates "default" style (with empty name) recorded from the associated map layer
and it is set as the current style. The instance must always contain at least one style (which is the current).

The style which is marked as current has no style data stored in its entry. This is to avoid duplication
of data as all data is stored in map layer and can be retrieved easily. Also when saving, the entry for
the current style will be saved with no data because everything is already saved by the map layer itself.

The class also features support for temporary change of the layer's style, ideal for short-term use of a custom
style followed by restoration of the original style (for example, when rendering a map with a different than current style).
