BREAKING CHANGE: The following REST endpoints have been removed, use W3C actions instead:
- /wda/touch/perform
- /wda/touch/multi/perform

-/**
- Perform complex touch action in scope of the current application.
- Touch actions are represented as lists of dictionaries with predefined sets of values and keys.
- Each dictionary must contain 'action' key, which is one of the following:
- - 'tap' to perform a single tap
- - 'longPress' to perform long tap
- - 'press' to perform press
- - 'release' to release the finger
- - 'moveTo' to move the virtual finger
- - 'wait' to modify the duration of the preceeding action
- - 'cancel' to cancel the preceeding action in the chain
- Each dictionary can also contain 'options' key with additional parameters dictionary related to the appropriate action.
- 
- The following options are mandatory for 'tap', 'longPress', 'press' and 'moveTo' actions:
- - 'x' the X coordinate of the action
- - 'y' the Y coordinate of the action
- - 'element' the corresponding element instance, for which the action is going to be performed
- If only 'element' is set then hit point coordinates of this element will be used.
- If only 'x' and 'y' are set then these will be considered as absolute coordinates.
- If both 'element' and 'x'/'y' are set then these will act as relative element coordinates.
- 
- It is also mandatory, that 'release' and 'wait' actions are preceeded with at least one chain item, which contains absolute coordinates, like 'tap', 'press' or 'longPress'. Empty chains are not allowed.
- 
- The following additional options are available for different actions:
- - 'tap': 'count' (defines count of taps to be performed in a row; 1 by default)
- - 'longPress': 'duration' (number of milliseconds to hold/move the virtual finger; 500.0 ms by default)
- - 'wait': 'ms' (number of milliseconds to wait for the preceeding action; 0.0 ms by default)
- 
- List of lists can be passed there is order to perform multi-finger touch action. Each single actions chain is going to be executed by a separate virtual finger in such case.
- 
- @param actions Either array of dictionaries, whose format is described above to peform single-finger touch action or array of array to perform multi-finger touch action.
- @param elementCache Cached elements mapping for the currrent application. The method assumes all elements are already represented by their actual instances if nil value is set
- @param error If there is an error, upon return contains an NSError object that describes the problem
- @return YES If the touch action has been successfully performed without errors
