+Added set_params function to all Locator types
+````````````````````````````````````````````````
+
+This was a bug fix targeted at making the api for Locators more consistent.
+
+In the old behavior, only locators of type MaxNLocator have set_params()
+defined, causing its use on any other Locator to throw an AttributeError *(
+aside: set_params(args) is a function that sets the parameters of a Locator
+instance to be as specified within args)*. The fix involves moving set_params()
+to the Locator class such that all subtypes will have this function defined.
+
+Since each of the Locator subtype have their own modifiable parameters, a
+universal set_params() in Locator isn't ideal. Instead, a default no-operation
+function that raises a warning is implemented in Locator. Subtypes extending
+Locator will then override with their own implementations. Subtypes that do
+not have a need for set_params() will fall back onto their parent's
+implementation, which raises a warning as intended.
+
+In the new behavior, all Locator instances will not throw an AttributeError
+when set_param() is called. For Locators that do not implement set_params(),
+the default implementation in Locator is used.

+API Consistency fix within Locators set_params() function
+---------------------------------------------------------
+
+set_params() function, which sets parameters within a Locator type instance,
+is now available to all Locator types. The implementation also prevents unsafe
+usage by strictly defining the parameters that a user can set.
+
+To use, simply call set_params() on a Locator instance with desired arguments:
+::
+
+    loc = matplotlib.ticker.LogLocator()
+    # Set given attributes for loc.
+    loc.set_params(numticks=8, numdecs=8, subs=[2.0], base=8)
+    # The below will error, as there is no such parameter for LogLocator
+    # named foo
+    # loc.set_params(foo='bar')
