Initializing help system before first use

Model.run

Purpose
Execute the model with optional input data. Raises RuntimeError if the model is already running on another thread.
Synopsis
function model.run(input_data=None, exec_params=None) -> dict
Arguments
input_data 
Dictionary of input data to pass to the model via the moselpy: driver. Keys are identifier names, values are Python objects convertible to Mosel types.
exec_params 
Execution parameters as a string ( "PARAM1=val1,PARAM2=val2") or list of strings ( ["PARAM1=val1", "PARAM2=val2"]). Sets values for model parameters (defined in the parameters block) and control parameters of modules/packages ( e.g., "mypkg.param=value"). The special parameter workdir defines the initial working directory.
Return value
Dictionary of output data collected via initializations to "moselpy:"
Example
Run with input and output data: 
model = mp.load_model("model.bim")
output = model.run(
    input_data={"x": 10, "arr": {1: 100, 2: 200}},
    exec_params={"VERBOSE": 1, "workdir": "/tmp"}
)
print(output["result"])
Further information
1. Input data is made available to the Mosel model via the moselpy: I/O driver in initializations from "moselpy:" blocks. No special compile options are required: the driver works with normally compiled models (no debug flags needed).
2. Output data is collected from initializations to "moselpy:" blocks and returned as a dictionary.
3. After execution, check Model.exec_status for execution status and Model.exit_code for the result value (from Mosel's exit statement, or 0 if not called). The exit_code is only meaningful when exec_status is ExecStatus.OK.
4. A model can be run multiple times. Model.reset is automatically called before each run to release resources from the previous execution.
5. Threading: The GIL is released while a model executes, so distinct Model instances can run fully in parallel across Python threads. While Model.run is executing on a Model, only Model.stop, Model.terminate, Model.is_running and Model.is_loaded can be called from another thread. Every other operation on that Model raises RuntimeError, as does a second call to Model.run. When the Model is not running, operations called from different threads are serialized.
