* Implement a basic YAML based parameter parser for ros2 nodes * Add README file * Fix the issues after moving from rcutils_yaml_param_parser to rcl_yaml_param_parser - rename folders from rcutils_yaml_param_parser to rcl_yaml_param_parser - rename project, header guards and include statements from rcutils_yaml_param_parser to rcl_yaml_param_parser - move type declaration in separat file and namespace new structures - Fix the code review comments from Mikael * Few minor changes - Changed "params" string to "ros__parameters" - Add -Wall, -Wextra and -Wpedantic falgs - Fix the compile warning with the new flags * Fix the changes made in the design of C structure - Remove the node_namespaces entry in rcl_params_t - Change the type of num_nodes and num_params to size_t * depend on libyaml_vendor (#236) * Fix cmake setting standard(C and C++) and add byte_array in C struct * Remove C11 so that it defaults to C99 * [rcl_yaml_param_parser] fix export symbols (#237) * add visibility macros * remove unused macro * Support for multi level node and parameter name spaces * Additional fixes and cleanups - Support for string namespace seperator - Provide parameter structure init function API - name cleanups * off by 1 * Call yaml_parser_delete() * fclose(yaml_file) * free() allocated paths * Call yaml_event_delete() * completely deallcoate string array * Few cleanup changes - Add install command into CMakelists.txt - Replace one of the zero_allocate with reallocate - Pass allocator state - Fix int32_t -> rcl_ret_t return value * Don't include unistd.h * Use size_t for array indices * Just pass the allocator in the init function

ROS2 rcl YAML paramter parser
Parse a YAML parameter file and populate the C data structure
The data structure params_st will then be used during node initialization
YAML parameter file should follow the yaml syntax shown below
NOTE: It only supports canonical int and float types
<node_namespace_string>: # optional
<node1_name>:
params:
<field_name>: <field_value>
<parameter_namespace_string>: # optional
<field1_name>: <field1_value>
<field2_name>: <field2_value>
<node2_name>:
params:
<field_name>: <field_value>
<parameter_namespace_string>: # optional
<field1_name>: <field1_value>
<field2_name>: <field2_value>
This package depends on C libyaml
