Creates a {@link ExtensionContext.Store} for a given {@code extensionContext}. A {@link
ExtensionContext.Store} is bound to an {@link ExtensionContext} so different test invocations
do not share the same store. For example a test invocation on {@code ClassA.testMethodA} will
have a different {@link ExtensionContext.Store} instance to that associated with a test
invocation on {@code ClassA.testMethodB} or test invocation on {@code ClassC.testMethodC}.

@param extensionContext the <em>context</em> in which the current test or container is being
executed
@return a {@link ExtensionContext.Store} for the given {@code extensionContext}
Creates a { @link ExtensionContext . Store } for a given { @code extensionContext } . A { @link ExtensionContext . Store } is bound to an { @link ExtensionContext } so different test invocations do not share the same store . For example a test invocation on { @code ClassA . testMethodA } will have a different { @link ExtensionContext . Store } instance to that associated with a test invocation on { @code ClassA . testMethodB } or test invocation on { @code ClassC . testMethodC } .
